This study seeks to investigate the impact of e-commerce on environmental sustainability. It performs a regression analysis of CO2 emissions, examining various determinants including internet users (Int) as a proxy to e-commerce, gross domestic product (GDP), trade openness (Trade) and to check the potential catching-up effect of GDP, we use GDP square. All variables are checked for normality using Kernell normality distribution curves and confirmed the normality of each variable used in the model. All data is collected from various data sources to get the most comprehensive data set. The study will do OLS regression along with Random effect and fixed effect estimator. The study encompasses 104 countries globally and it will span the period from 1991 to 2021. The results indicate that the expected signs are confirmed and statistically significant.
